Greetings and welcome to our site! ¬†There are a number of crystals out there with energies suited to issues of creativity, temper, calmness, and positive-thinking. ¬†The following are the best crystals I can think of for your specific question. ¬†I have tried to find a number of stones that each deal with multiple issues from your question.

The first stone that comes to mind that would assist you as a musician is nurturing Citrine. ¬†Citrine is a crystal for the Solar-Plexus Chakra that supports creative endeavors. ¬†Citrine carries a warm and productive vibration that can provide optimum conditions for those needing a boost in creativity and inspiration. ¬†Citrine can also offer help for those suffering from blockages of both energy and creativity. ¬†Citrine's bright energy can combat negativity at the core level. ¬†You can see our Citrine items at the following page:http://www.healingcrystals.com/Listing_by_Stone_Type/Citrine/

Working with the Heart Chakra, Green Aventurine is a great stone for enhancing creativity and motivation. ¬†Meditation with Green Aventurine can bring new inspirations that come either during the meditation or afterwards. ¬†Keeping a piece of Green Aventurine in the purse or pocket can help to encourage unique perception and innovative ideas. ¬†Green Aventurine can also raise confidence to pursue projects and goals to their conclusions. ¬†If you'd like to look at our selection of Green Aventurine, Follow this link:http://www.healingcrystals.com/Listing_by_Stone_Type/Green_Aventurine/

The perfect stone for attracting calming energies to oneself is, in my opinion, Lithium Quartz. ¬†Offering its soothing vibration to balance chaotic vibrations in the emotional and mental bodies. ¬†Regular meditation with Lithium Quartz can help one to ultimately attain inner peace and social serenity. ¬†Lithium Quartz can help with anger management issues as well as overall calmness. ¬†Lithium Quartz can help us to recognize that our will is not always the correct will and that sometimes, we need to accept the perfection of the Universe. ¬†Opening up to this idea allows positive thoughts to come in where negativity previously has dwelled. ¬†If you're interested in seeing some Lithium Quartz, we have some here:http://www.healingcrystals.com/Listing_by_Stone_Type/Lithium_Quartz/

Another great stone for attracting positive vibrations is Topaz. ¬†Vibrant Topaz enhances all mental processes and can help with creativity, optimism, perseverance, and manifestation. ¬†Also known as "Imperial Topaz", Topaz is known as a general stone of good luck and prosperity. ¬†By activating the lower three chakras, along with the Crown Chakra, Topaz can provide a centering of otherwise scattered energies, which can offer some help for each of the states you mentioned in your question. ¬†Topaz can also bring one to an understanding of the connections between the macro and the micro. ¬†Our Topaz can be seen on this page:http://www.healingcrystals.com/Listing_by_Stone_Type/Topaz/
